BAD SERVICE AND COMMUNICATION

I did a online upgrade on the 22nd of May 2018. I have done online upgrades regularly and almost everytime received my new device the next day. As I did not hear anything I phoned customer care and were told that the transaction was not confirmed yet. The lady even phoned me on the 22nd after I received the confirmation sms to inform me that there is a system error and the device on the sms is my old device but that I will recieve the device as per our telephone conversation on the upgrade. I also did the activation on my phone while we were doing the upgrade. Now I am being told that they will phone me to do the confirmation and that the device were not even dispatched yet! I am so disappointed, have been a loyal client for many years and have more than 10 line with them. I am now seriously considering moving to another more reliable service provider, worst service ever!
